"Didn't think about it," The Master said, thankful for the assist upwards and quickly filing away the fact that the assault was likely an accident as yet another encouragement in the long process of winning himself back onto Lucy's good side. It was rather sweet for her to think that she could kill him with a frying pan, really, and while she didn't so concerned so much as annoyed at him just showing up out of the blue to get pummeled, he figured that it was probably another point in his favor that she even so much as thought to voice the fact he could have died as something to be concerned about.
"I thought you might want a lift," He said, offering her a smile that reflected his self-assurance in the fact that she wouldn't even think to turn him down once he'd made the full offer. "The Rani suggested putting together a safe area where the Gremlins won't be able to get in by hooking our TARDISes together with UV lighting, and I thought maybe you'd want a quick run down there so that you don't have to brave the transit once we get everything in place."
Also, he'd invited her to see his TARDIS, and she'd yet to come on her own, so he might as well take the opportunity to show it off as well. He had to wonder if she'd so much as guessed that it was there in the room with them at the moment since one so used to seeing the Doctor's TARDIS usually was surprised by one that properly blended in.
"That is, unless you'd rather fend them off on your own, then I could leave just as easily as I came," Even the Master on his best behavior couldn't help but attempt a wee bit of reverse psychology. Manipulation was one of his greatest weaknesses.
